suggestion on initial IDE-boot configuration
Dear listmembers,
my experiences with my U60 lead me to the following suggestion:
-> put a default "ide=nodma" as kernel parameter on SPARC
-> make the user / the configuration enable dma via /etc/init.d/XXX
why?
U60 cannot cope with udma-modes (AFAIK, on those Promise controllers I have tested) > 2. If you i.e. use an external controller that enables max-dma-speed by default, the installation will always fail - assuming you want to install on an ide-hdd.
If this would be an installation option (maybe with a test-structure ...) IMHO ide-installation could run smoothly.
Somebody who does not know about the potential problems will never be lucky with this. Any hdd-setup will fail due to the too high speed drive-access due to the dma-mode.
Take care
Dieter Jurzitza
